The Featured Image from URL (FIFU) plugin for WordPress is vulnerable to unauthorized access of data due to a missing capability check on the fifu_api_debug_posts() function in all versions up to, and including, 5.2.7. This makes it possible for unauthenticated attackers to read private/password protected posts.
Add your gear to cvedb and we'll alert you only when a vendor you run ships something exploited.
